Did You Know Heat Pumps Need a Special Thermostat?

Drain Cleaning

It would require work to locate a superior option for year-round comfort than an air-source heat pump. Heat pumps work as both air conditioners and heaters, giving you the temperature control you need, no matter the season. As a plus, heat pumps require less energy to run when it comes to heating than most other systems, such as furnaces. The U.S. Department of Energy estimates that a family of four can save 30%-40% off their yearly heating costs when they switch to a heat pump.

If you think a heat pump in Bay Village, OH will work well for your needs this coming year, contact our installation experts at Westland Heating and Air Conditioning. We can also provide repairs for heat pumps and answer any questions and concerns you may have regarding them.

The heat pump thermostat

We often hear questions about how heat pumps differ from other systems—specifically from air conditioners. Among these differences, we discuss the special thermostats that heat pumps need. Why do heat pumps require a particular type of thermostat that’s different from an air conditioner’s?

The reason is that heat pumps must control both heating and cooling. To switch from one to the other, the thermostat needs to signal the reversing valve to change the direction of the flow of refrigerant. Where a standard AC thermostat uses four wires (hot wire, compressor and outdoor fan wire, indoor blower wire, battery wire) to run the unit, a heat pump thermostat requires a fifth wire to handle the change in the reversing valve. These wires are usually color-coded, and the reversing wire is the brown wire.

Don’t try this at home (unless you have experts in your home)

However… please don’t use this information to attempt to install or repair a thermostat on your own. Even if you think you’ve managed a repair correctly and the thermostat appears to be working, even a slight miscalibration can lead to serious problems with your heat pump. It will incorrectly sense the temperature in your home and begin to shut on and off at the wrong time. This means less comfort for you and more wear and tear on your heat pump.
